Date: In general Cobol has two data types. It supports numeric and text. But modern applications has various data types.
Typically speaking, Date. This is not a number. This is date.
03 DATE1 PIC 9(6)
This is numeric. But real date needs ‘/’. So we need to write extra code to handle date.
Fractions: For example ’52/3′ Cobol does not understand directly this fraction.
So we need to write separate program, using unstring to convert it into fractions.
Dynamic String: In modern applications we get variable strings. For this there is no data type. So we need to write extra code to handle this.
